Abstract
Embodiments of the invention relate to a composite hydrogen storage material comprising active material particles and a binder, wherein the binder immobilizes the active material particles sufficient to maintain relative spatial relationships between the active material particles.
Claims27
A composite hydrogen storage material comprising:
- active material particles, capable of occluding and desorbing hydrogen;
- and
- a thermoplastic binder;
- wherein the binder elastically immobilizes the active material particles sufficient to maintain relative spatial relationships between the active material particles before, during and after any occluding and desorbing of hydrogen;
- and
- wherein the composite hydrogen storage material is capable of withstanding a force produced by a particle strain during occlusion and desorption of hydrogen by the active material particles, sufficient to provide a load bearing member independently or within a storage vessel.
3 more elements
A composite hydrogen storage material comprising:
- active material particles, capable of occluding and desorbing hydrogen;
- a thermoplastic binder;
- and
- one or more additives;
- wherein the binder elastically immobilizes the active material particles and the one or more additives sufficient to maintain relative spatial relationships between the active material particles and one or more additives before, during and after any occluding and desorbing of hydrogen;
- and
- wherein the composite hydrogen storage material is capable of withstanding a force produced by a particle strain during occlusion and desorption of hydrogen by the active material particles, sufficient to provide a load bearing member independently or within a storage vessel.
4 more elements
A composite hydrogen storage material comprising:
- active material particles, capable of occluding and desorbing hydrogen;
- and
- a thermoplastic binder, the binder elastically immobilizing the active material particles sufficient to maintain relative spatial relationships between the active material particles;
- wherein the composite hydrogen storage material comprises a porosity from about 0.1% to about 50%, and wherein the active material particles comprise a packing density that is at least about 40% of the composite hydrogen storage material;
- and
- wherein the composite hydrogen storage material is capable of withstanding a force produced by a particle strain during occlusion and desorption of hydrogen by the active material particles, sufficient to provide a load bearing member independently or within a storage vessel.
3 more elements
A hydrogen storage system comprising:
- (A) a storage vessel;
- (B) a composite hydrogen storage material disposed in the storage vessel, wherein the composite hydrogen storage material comprises:
- active material particles, capable of occluding and desorbing hydrogen;
- and
- a thermoplastic binder;
- wherein the binder elastically immobilizes the active material particles sufficient to maintain relative spatial relationships between the active material particles before, during and after any occluding and desorbing of hydrogen;
- and
- wherein the composite hydrogen storage material is capable of withstanding a force produced by a particle strain during occlusion and desorption of hydrogen by the active material particles, sufficient to provide a load bearing member independently or within a storage vessel;
- (C) at least one port for communicating with an external device.
